Abstract

Abstract

The photodissociation dynamics of AlO at 193 nm is studied using time-sliced ion velocity mapping. Two dissociation channels are found through the speed and angular distributions of aluminum ions: one is one photon dissociation of the neutral AlO to generate Al(2Pu) + O(3Pg), and the other is two-photon ionization and then dissociation of AlO+ to generate Al+(1Sg) + O(3Pg). Each dissociation channel includes the contribution of AlO in the vibrational states v = 0-2. The anisotropy parameter of the neutral dissociation channel is more dependent on the vibration state of AlO than the ion dissociation channel.
